A nasty afternoon shower rolled into downtown Houston shortly after 2 p.m. Saturday afternoon, but a National Weather Service spokesperson said it wouldn't stay long.

Brian Haines said the storm was driven by daytime heating, and it could produce an inch or two of rain. He said the weather is expected to clear out later in the afternoon or early in the evening, when the sun goes down.

Haines said there is a chance for more late afternoon thunderstorms on Sunday.
